My invention relates Vto dumpingtrucks and particularly to automobiledumping trucks, the main object of the invention beingy to improve theconstruction of the same. l

Automobile trucks have heretofore been constructed with tilting' ordumping bodies and with manually actuated means for operating the same,and thereare many dumping automobile trucks of this type in use at thepresent time. VA truck of the type referred to includes as part. of thevbody-operating mechanism'a main shaft mounted on the chassis of thevehicle andconnected with the tilting body by suitable gearing through`which rotation of said shaft operates vthe body, said shaft beingmanually actuated by means of a crank handle applied to one end thereofat one side of thefvehicle. YWith 2O most trucks of this type it hasheretofore been necessary to provide means forlocling the body in itstilted position and sometimes, also, to provide means for lockingthebody in its lowermost or horizontal position. vMy

invention provides a self-contained unitary attachment for the actuatingshaft of a standard automobile `dumping truck body-operating mechanismofthe class just referred to by means of which the same may be powerdrivenin eitherdirection to positively raise and lower the body, and by whichsaid shaft is normally locked against rotation in` either direction.

Another feature of my invention consists 35 in providing abody-actuating shaft journaled on the chassis of the vehicle carrying aworm gear meshing with a worm thatA is driven by an electric motor, saidworm and electric motor being also'mounted 'on the chassis of thevehicle. In the best form 'of my invention means is 'provided byadjustment of which the motor kmay be caused to drive the worm in'eitherdirection. In practice prefer to construct the motor so that 5 itsbrushes arerotatably adjustable with relation to the armature of themotor to control and determine the direction in which the latter isoperated to drive the worm.

Thus in the preferred form of my invention the engagement of the wormlwith the drive a shaft 13 to which is fixed one or moreV arms 14,7eachconnected by a link 15 with the forward end portion of the body 5.

On the seat 6 isA kmounted body-operatingymechanism includ- 1 ing -a main shaft 7 carrying a pinion-8 operatingthrough the usual gears 9, 11 and l2 to .The main shaft 7 extendsoutwardly beyondthe chassis 1 andv seat 6 and has its outer end portion,made square as at l6f to 90 "receive upon ita crank handle,l not shown,by

meansof whichQthe Ashaftq? has heretofore been manually rotated By meansof this tated in one direction to adjust the body 5 5 into its tiltedposition, indicated by dotted lines, and in the opposite-direction tolower it againinto its full line position. So far as fescribed theconstruction and operation are the same as heretofore. Also, it has beenfem-fica;

i iis'fr'ee to rotate relatively tothe gear-bok.

W' vAtoneen tren customary,f heretofore, toprovide aibracket 17 luponthe outside of the seat 6 adjacent fthe shaft 7 on which a pawl, notshown, wasH pivotally mounted by means ofa bolt 18, said pawl engaging alratchet wheel, not shown,

j' I-n proceeding in accordance'with iny'in-l;

Y yventionv I dispense with the ratchet wheel, y its pawl, and thecrankhandleabove referred f Vt0,and provide electric" driving unit at` Itachment including a gearv boXj19 cornprisingr V twoapproximatelyfcounterpart sections 21 1 :and 22 fastened together`bymeansof screws 23".

`The other `circuit .terminals of Ytheswitch 41 and of motorz29`aregrounded, l respectively,by wires 42 and 43 on'thefmetal -z' [chassis 1.Y y i Y `It will thus be clear that when rswitch. 41 is inclosedconditionthe circuit of motor-1,29 is complete and'that if handlever 37is posi'- "tionedratthe limit of `its movement inone directionv thearmatureSO will be driven in ,through gear 24 d ol-f'the worinchamber26. the-gear i Y box 29 is made with (interna-lV flangesproviding aseat for the f'rame'of motor 29 which fislalso `made @with anexternal apertured one direction and if at the'limit of its move* vmentin the opposite direction said armature will be driven in the oppositedirection. Thus by means of hand lever 87 the motor 29 may be adjustedto drive the worm 27 in either direction.

'It will, of course, befclear that rotation of lthe worm 27 *inV onedirection operates andthe usual body operat! ing mechanism i above`described, :to tilt the .body 5,' while VVrotationof'v the worm in theopposite direction returns body to its normal horizontal position. a
